50.5 EXTRACTION OF METALS METALLURGY Chemistry . The process of extracting pure metal from its ore is known as metallurgy. . Since, the nature of the ore and also the properties of different metals are different, therefore, it is not possible to have the universal scheme which may be applicable to all the metals.
